To all whom it may concern:

Be it known that I, AROHIBALD M; WHIP- PLE, a citizen of the United States, residing at North Adams, in the county of Berkshire and State of Massachusetts, have invented certain new and useful Improvements in Systems of Glazing; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which'it appertains to make and use the same. I I

My invention relates to an improved system of glazing or securing window-glass in place within a sash, andis designed for either plate-glass work, wherein a single pane is employed, or in millwork or general glazing, wherein a plurality of small panes are used.

The object of the invention is to provide a system or mode of glazinginvolving mechanical fastening and sealing means of such a nature that the pane or panes of glass will be held'securely in place and may be set or reset without the aid of skilled help and without the necessity'of working upon the outside of the sash or removing it from the windowframe, and, furthermore, to provide sealing means which shall be neat and ornamental in appearance, form'an air and water tight joint, which may be applied and removed Without injury in setting or resetting a pane,

and which will not be affected by rubbing on cleansing, but will, on the contrary, when pressure is brought to bear upon the exposed surfaces thereof seal the joint more securely and effectively.

A further object of the invention is to provide a system or mode of glazing for millsash and general Work whereby the panes of glass are firmly held without the use of adhesives and may be inserted and removed from the interior of the building, whereby the ordinary practice of setting the glass prior to 7 7 of Fig. 6.

without the use of adhesives and, toform a close joint \Vith these and other minor objects in View, which will appear as the nature of the invention isbetterunderstood, the invention consists of certain novel features of construction, combination, and arrangement of parts, which will 'be hereinafter more fully described, and particularly pointed outin the appended claims, reference being had to the accompanying drawings, in which- Figure 1 is an inner side eievational View of a window-sash, showing the mode of employing the invention for securing plate-glass in place. Fig. 2 is an enlarged detail horizontal section through one of the side rails of the sash. Fig. 3 is an enlarged detail vertical section through the bottom rail of the sash. Fig. 4 shows two views of a sealing: strip, showing the normal and braided positions of its free fold. Fig. 5. is a'view similar to Fig. 1, showing the mode of employing the invention for mill-sash work and general glazing. Fig. 6 is a detail cross section through a portion of the sash shown in Fig. 5 on the line 6 6 thereof. Fig. 7is avertical section through the center munnion on line Fig. 8 is a detail perspective view of the sealing-strip interposed between the sections of the munnion, and Fig. 9 is a detail view of a strip designed for circular 4 sealing. p

Referring now generally to the several figures of the drawings, and particularly to Figs.

1 to 4, inclusive, the numeral 1 designates the stiles, and the numerals 2 and 3 the top and bottom rails, of a window-sash having around the inner edges of said stiles and rails a rabbet, the plane face or shoulder 4 whereof, Whereon the glass pane is adapted to seat, is inwardly disposed, so as to adapt the panes tobe set and reset from the inner instead of erlng 8 is folded longitudinally upon itself to form opposite plies or layers, which are cemented to the opposite sides of the body-strip (land are connected at their outer edges by a fold or return portion 9, which, as shown, extends beyond the outer edge of the said body-strip 6 to form a free flexible or plastic portion which is adapted to yield or give under pressure and seal the joints or crevices between the pane and rabbet more securely the greater the pressure brought to bearthereon during the process of washing and rubbing the panes in the cleansing and drying operation. These sealing-strips extend continuously aroundthe rabbetand are cemented or otherwise secured thereto, so as to be held againstdisplacement. The glasspaneobears upon the inner side of said strips, which are outwardly disposed, and also upon similar strips laid against the inner side thereof and between the same and the molding strips or beads 10, which are secured to the inner faces of the sash, stiles, and rails and serve to retain the inner series of sealing-strips and the glass pane in position. The sealing-strips upon opposite sidesthat is, upon the inner and outer sides of the glass pane-are disposed so that the outer edges of the bodystrips or backings thereof lie flush with the outer surfaces of the rabbet 4 and moldingstrips 10, with the plasticfold or return portion 9 thereof projecting a short distance beyond said surfaces. From this construction it will be readily seen that in the process of cleansing the glass pane should any pressure he brought to bear upon said sealing-strips the plastic folds or return portions 9 thereof will be braided or forced inwardly, causing said portions to spread to a greater or less degree, according to the amount of pressure brought to bear thereon, and to recede into the crevices or spaces between the pane and the rabbet and molding-strips and more securely and effectually close said crevices or joints to prevent the access of water thereto, whereby an absolutely air and water tight joint is afiorded under all conditions of service.

The molding-strip 10 at the bottom of the sash may be and preferably is of a form different from its fellow strips and is preferably inclosed within or covered by a layer 10 of tin-foil, which may be suitably colored to conform to the color of the remaining strips and sash to provide a neat and tasty appearance, the tin-foil in this connection acting as a water-shed to prevent any moisture or water of condensation flowing down upon the inside of the glass pane from'gaining access to the joint between said strip and pane. By constructing and arranging the parts in the manner stated I am enabled to secure the largest-sized plate-glass firmly within the sash-frame and to provide an absolutely air and water tight joint.

The purpose of arranging the shoulder of the bead 410 face inwardly instead of outsash parts.

wardly, as in the ordinary construction, is to provide for the convenient setting or resetting of the pane from the interior of the sashframe, thus rendering it unnecessary to perform this work from without or to remove the sash from its frame or casing, and such arrangement also obviates the necessity of first setting the glass plane within its sash before the latter is applied to its frame, whereby all danger of fracture of the pane during the transportation of the sash from the mill or factory to the building to which it is to be applied is entirely avoided. I employ wooden molding strips and semiflexible or elastic body portions for the sealing-strips in preference to metallic strips, because they are not liable to rot or corrode, are easier secured in position and fitted to form closer joints, and, moreover, possess a certain amount of elasticity with sufficient rigidity to allow the glass pane to have a slight vibratory play under pressure without loosening the fastening connections, whereby liability of fracture of the pane is reduced to a minimum. The wooden strips are adapted also to more closely follow or conform to the irregularities in the panes of glass, so as to render clamping pressure on the glass unnecessary. By constructing and applying the sealing-strips in the manner stated each strip forms a smooth metallic waterproof surface, which effectually hermetically seals the joint and at the same time obviates all liability of warping of the The construction also provides a neat and tasty fastening for holding the pane securely without the necessity of springing it and which is adapted to form a yielding cushion, against which the glass may vibrate to a slight extent to reduce the liability of breakage thereof. The sealing-strips may be colored to correspond to the color of the sash or building and keep the surface of the glass clean, as there is no putty to wash off. The fastening is very advantageous, in that it may be easily repaired or renewed without weakening the sash, as the cleavage is perfect, and the sash may be washed or otherwise cleansed without liability of loosening or detaching any of the parts of the fastening, but, on the other hand, with the advantage of making the joint more perfect. Furthermore, the sealing-strip when made of tin-foil forms a practically plated surface, which is bright and attractive and conducive to the entrance of light, and it also makes possible invisible lapping at the corners and gives additional security Where the wooden strips meet. By arranging the sealing-strips upon opposite sides of the glass pane it will be readily seen that the pane is cushioned in both directions and that the joints are sealed against the inlet of air or water from without. The manner of applying and removing the pane will be readily understood from the foregoing description, and it will be seen that my improved construction permits of ready insertion and removal of the pane without injury to the sealing or molding stripsor to the body of the sash.

Inthe application of the invention, as shown in Figs. 5 to 8, inclusive, to -sashes of that kind provided withone or more pairs of bars ormunnion's ll tohold a plurality of panesof glass the construction is essentially the same; except that the munnion 11 is divided, having a fixed portion 11, which has its inner face extending'flusli'with the inner face or shoul-' der of the rabbet 4, and a removable section ll", which covers and holds the adjacent ed ges of the glass pane in place. Upon the inner side or face of the munnion I also provide a.

munnion, said strip acting to bear upon thepane to hold it'in' contact with the said seal-' ing-strip, while the'screws act in the nature of stops interposed between the meeting edges of the panes to hold them against movement and properly spaced apart. The advan g of the foregoing construction are that it permits of the ready application and removal or setting and resetting of the panes of glasswith ease and facility and without marring the appearance of the sash or injuring the sealing devices. Such construction also permits of the ready setting of the glass within the frame from the interior of the building, which renders itunnecessary to remove the'sas'h from its frame to work upon the exterior of the building or to set the panes of glass Within the sash prior to mounting the latter within its frame. As a large proportion of the glass panes in sashes completely fitted at the sash factory or mill are brokenwhile being trans.-.

ported therefrom to the place of use, it will be readily seen that my invention is adapted to effect a great saving'in repairsand in the re placing of broken glass'and that it is also adapted to prevent loss of heat within a room or apartment, as a broken pane of glass may be quickly removed and a new one substituted therefor without the necessity of lifting erably make such portion of felt but'any other kind of material suitable for the purpose may be employed in lieu thereof.

Fromthe foregoing description, taken in connection with the accompanying drawings, the construction,- mode of operation, and advantagesof'my*invention will be readily understood.

4 Changes inthe form, proportion, and minor details of construction may be made within the scope of'the invention without departing from thespirit or sacri ficing'any 'of the advantages thereof;

Having thus described my'invention, what I claim, and desire to secure by Letters'Patent, is I l.
